Beware Black Widow

The Fiend (also known as Beware My Brethren) is a 1972 British horror film produced and directed by Robert Hartford-Davis and starring Ann Todd, Tony Beckley and Patrick Magee. It was written by Brian Comport. The film is set against a background of religious fanaticism and, as with other films directed by Hartford-Davis, includes elements of the sexploitation genre of the early 1970s.
